Chile eruption: How volcanic ash stops a jet engine

The video explains how abrasive particles can erode parts of an aircraft, particularly affecting jet engines. It describes the high temperatures in jet engines and how glass particles can melt and adhere to turbine blades, potentially causing engine stalls. The video also outlines a cooling process that allows engines to be restarted by cracking and dispersing the molten glass.

What is the consequence of molten glass sticking to turbine blades?

How does turning off the engines help in dealing with molten glass?
